11 Claims.

This invention relates to a machine for whipping tough nougats, frappes and the lighter type substances such as marshmallow, cream and mayonnaise.

Objects of the invention are: to provide a machine for whipping in an improved manner more or less liquid edibles and/or to effect an improved agitation or mixing thereof; to provide an all-purpose mixer and whipper, wherein the entire whipping mechanism is elevated and lowered at will and wherein the entire whipping tank may be rotated in opposite directions in order to dump the load onto table tops at either side of an aisle along which the device is movable; this portability of the device adapting it for being conducted to the fires where the syrups are heated, instead of carrying the hot syrups long distances to the machine; to provide a machine possessing the advantage of being self cleaning due to the incorporation of automatically operated scraping bars which rub the sides and ends of the machine or are manually operated, during the mix ing operation, by turning a hand wheel exterior of the tank.

More specific objects of the invention are: to provide an improved beater wherein the whipping rods are mounted upon the mixer shaft in a corkscrew or serpentine fashion from one extremity to the other, thus avoiding one-sided slapping of the syrups or mixes so common in ordinary mixers or beaters. In the latter connection there is less wear on belts and motive power due to the evenness in which the mix is beaten; and to provide in a machine of the character stated an unusual assembly of novel combination and arrangement of parts better suited to perform the functions for which a device of this character is intended.

Other objects, advantages and features of invention will hereinafter appear.

Referring to the accompanying drawings, which illustrate what is at present deemed to be a preferred embodiment of the invention,

Fig. 1 is a side elevation of the complete apparatus.

Fig. 2 is an end elevation looking from right to left of Fig. 1.

Fig. 3 is a horizontal section on line 3-3 of Fig. 1, on a reduced scale.

Fig. 4 is an enlarged perspective view of the scraper, separately shown.

Fig. 5 is an enlarged, sectional perspective illustrating a portion of the operating and mounting means for the scraper.

Fig. 6 is an enlarged perspective view of the beater member.

Referring in detail to the drawings, the main parts of the apparatus are, the portable, elongated base A, tubular extensible standard B upstanding from said base at one side of the midlength thereof, the tubular treating tank C carried by said standard, the motor D also carried by said standard, and the power transmitting means E whereby said motor is operatively connected with the treating mechanism contained within said tank.

The tank C is turnable about a horizontal axis for a distance of degrees in either direction from its normal position so as to swing its intake and discharge hopper portion I 0 to a downwardly directed position for dumpingpurposes. With this end in view said tank is provided at its left end as viewed in Fig. 1 with a large cylindrical extension I I turnably contained within the main journal I2, which is of a conventional two-part character, comprising a cap I3 bolted to a base I4, said base, in turn, being provided with a foot portion I5 seated for turnable adjustment upon the adjacent portion of the vertically adjustable standard body I6. Said foot portion I5 of the bearing section I4 has leading upwardly into it a screwthreaded socket into which screws the threaded portion of an axis bolt I1 around which the tank 0, motor D and power transmission E are turnable.

As an auxiliary support for the horizontally offset tank C a brace I8 is provided thereunder, saidbrace having a saddle portion I9 to underlie the tank and a downwardly directed leg 20 swingably attached at 2| to the standard body I6. Said saddle portion I9 is provided with a winged screw 22 to seat within a suitable recess provided therefor in the bottom of the tank. This nut is loosened and said saddle swung downwardly preparatory to either turning the tank about its horizontal axis for dumping, or for turning it in a horizontal plane.

As an additional means for preventing the tank from rotating about its axis a horizontally slidable bolt 25 is'provided having bearings 26 and 21 in the aforesaid foot portion I5, said bolt having an operating handle 28 and being normally held by a spring 29 in engagement with socket 311 or 3| formed in a circular member 32 intervening between the body portion of the tank C and the journal I2.

The motor D has an upwardly directed bedplate 33 which is apertured to receive the axis bolt I1 and rests upon the inner side of its head, said bedplate being fastened to the bolt by a pin 34 to turn therewith when the motor and tank are bodily swung in a horizontal plane around said axis bolt. The motor is shown having hanger brackets 35 bolted to said bedplate at opposite sides of the head of the axis bolt. Above the standard body IS a pin 36 prevents rotation between the axis bolt l1 and the foot portion [5 of the bearing section M.

The vertically adjustable standard body 1.6 carries a pair of downwardly directed limbs assuaably related to the tubular standard posts 39. A crosshead is fixed to and between the upper portions of said posts 39. p 4

A conventional gear mechanism H is provided for rotating a vertical screw shaft within a threaded bore provided therefor in the 'crossheau 40 to elevate and lower the standard body '15. This gear mechanism includes a worm gear 44 fixed to the screw shaft 42, said gear meshing with 'a, worm 45 operated by a handwheel 46 having a handle portion 41. Cross bar 48 extending between limbs 38 formsa bearing for the upper end of the screw shaft .42 (see Fig. 2)

The outer end of th cylindrical tank C is surroundedlby a radial flange 50 having circumferentially paced apart screwthreaded sockets with which cooperate winged screws 52 whereby a cover plate 53 is detachably secured to the tank, said cover platehaving pairs of juxtaposed ears 5 4 with which saidwinged screws cooperate. Said cover plate, best shown in Fig. 5, has a central, apertured, outwardly projecting bos 55 with an axialbearing passage through it within which is turnablyfitted a stub-shaft 56, having a tapered outer end portion to which is fixed a handwheel 51 parrying a handl 58-. Said stub-shaft 56 has a, diametrically enlarged inner end portion 59 u c l ished w iha ke v lug 60 which projects a l .ou ar ih efmmr v in Fig. 4 det a-iled a scraper Shaving at one and a w ena t. ng o t on 5. a d. its oppq e n m l h r n stru ture were .wi hltheb arii as ru ur .55 a e d e iq v. p pdsi ei e d a arm 61., e-a m 68 m 'f i ra i .s i etr -bi es ru r s -sc ese f. me b r wmr e d by m a q e 'l ,e i iw s mperl de 6 u it dr thearms '61 and 6 8. as shown, and the bolt and t' r e n ml t. o.

The frame of Dri'siiig'a pa'rallel side'portib'rislll with ebnvef 'in portions the portable base A is shown'comcarrying Ibe'am member 88 which join each other at the front end, the front wheel 89 being supported by and between the latter beam portions; and diverging rear portions 90. To the outer ends of said portion 90 are hinged at 9| arms 92 which are swingable in a horizontal plane to permit the rear ground wheels 93 they carry to be trailed in such a manner as not to impede turning movements of the portable base A. The arms 92 carry stop fingers 94 abuttable against the beam portion 90 to limit the swing of the arms 92. t I

Near its front end the portable base A carries a tubular standard 95 within which is fitted for vertical adjustment the leg 96 of a table top 91, said leg being maintained in the desired vertically adjustable position by means of a thumb screw 98. "Said table top is vertically beneath the hopper ID of the cylindrical tank when the latter is positioned as shown in Fig. 1, so that, b rotating the tank half a turn about its axis and then withdrawing the cover from thehopper the contents 0f the tahk may be dumped into a container supported upon said table top. I I i The cylihdrical tank extension H is provided with aperipheral flange I If at its outer end and also with a central bearing extension fig, these two parts being integral therewith, so when the cap portion of the journal structure is bolted in place the vaneus mechanically rotatable and manuany turnable parts are maintained their assembled relation. I v

Referring to other structural details, between the foot portion 15 of the rennin structure ill and the houew standard body 'I 6 see also Fig.3), is mt'er'poseaa weafi'ng pla'te 99 welded to the upper edge offs'aid'stajfidai-d may 15. 'Also Betweengthe ho'llovv standard body is an the tea plate 33 o'fftlie motor is interposed a wearing plate H30, welded to the lower edge of said standard body 16, These two plates provide adequate bearing surfaces when "it desired ts 'rbta'te the un ts o, 'D afiq E smut "axis "at ten 11.,

Relative to the operation, cggisiden'n'g the device in tlie pbsitionshow'n In 1, the hopper m s r cin uuiiwara y in position for the material to'b'e introduced theret'hrdugh into the 'tank 0 for treating. Since the volumes'df "certain types fo'f materials to b ej'trea'tedincrea'sefismuch a 300% when they are whipped the tank C must be not fined ti) suchfan ext as to interfere with this e'ip'alns'io'n. When tre atirig hot "syrups, "maislrm'allo'wfand "fra'pps, thefnachin e will be lowered by operatio'nbf 'theliand'whel 48 in order-to avoid using a step-'1adaer;in carrying the hot liquids in) to 'the =hcpper which act i'v'diil'd irrcrease the danger of thop'rialtor bin'gbu'fn'ed. As "a further safeguard against bums while introducing and removing nukes, tlfe ho per is made verycommodious.

Preparatory to fillin'g'the'mix into the hopper, the cover 53 will be-screwed tightlyontothe outer end of the tank 'the saddle or brace l8 will be screwed up tightly and the sliding bolt 25 will'be inserted into the aperture-30 of the circular'member 32.

The power will then b turned on andtlfe muss whipped, this operation taking place-at'the point most convenient to the material -to be suppli'ed, as for example, close to the stoves where the syrups are heated, thereby avoiding having to hau l'kettles of h'otfsyrup irom remote-pointsto wherethe'inachine'islo'cated.

After the whipping or beating has been completed the power is turned off and the machine is pushed by means of the handles lill to the table tops onto which the mass is to be poured. When the tank C has been brought to an overhanging position in relation to the selected table, the set screw 22 under the tank is loosened, the saddle I9 is swung downwardly outof the way, the bolt 25 is retracted and the tank C is then rotated 180 degrees in either direction thus bringing the upper aperture 3| (Fig. 1) into registry with the bolt 25, then the hand wheel 46 is turned in the proper direction to lower the tank so as to bring the hopper down as close as desired to said table top, whereupon the hopper handle I82 is operated to withdraw the hopper cover I03, causing the contents of the tank to be discharged through the downwardly directed hopper i0, onto the underlying table. In order to discharge that portion of the contents of the tank which adheres to its Walls the hand wheel 5? will be rotated in the direction opposite to that in which the material was whipped, thereby dragging the last adhering residues to the edge of the hopper to fall therefrom onto the table.

Should it be desired to retrieve the beaten mass the machine need not be moved from the spot where the whippin ntook place, since the adjustable stand 9! can serve to support an empty container to receive the mass for future use.
